Key result
A new dual-filament activation paradigm highlights a bi-directional mechanical feedback where thick filament activation regulates and is regulated by muscle contraction and mechanics.
Why the study?
Growing evidence indicates that thick filament activation plays a role in striated muscle fine regulation and its impairment is linked to severe pathologies, prompting a focus on the proposed mechanosensing mechanism.

Should not yet change practice; leaves open whether thick-filament mechanosensing can be targeted in cardiomyopathy.
Highlights the emerging dual-filament activation paradigm in striated muscle, emphasizing the crucial role of thick filament mechanosensing in regulating muscle mechanical performance.
Lorenzo Marcucci (2023) conducted a review in Striated muscle contraction. Thick filament activation and mechanosensing mechanism was evaluated. A new dual-filament activation paradigm highlights a bi-directional mechanical feedback where thick filament activation regulates and is regulated by muscle contraction and mechanics.
